| Abstract
|
| Objective To explore the impacts of combined application of iron, manganese, and boron microelements on the yield and quality of C.dahurica(Turcz.) Maxim., and to furnish a rational fertilizer scheme for the standardized field cultivation of C.dahurica(Turcz.) Maxim.. Methods C.dahurica(Turcz.) Maxim. seedlings were gathered from Chengde City, Hebei Province, and subjected to a pot experiment. The "3414"experimental approach was employed to design the fertilization levels of iron, manganese, and boron microelement application. Growth indicators were measured post-harvest. The contents of pharmacological components such as caffeic acid, ferulic acid, and isoferulic acid were determined by HPLC, while the total phenolic acid content was measured by UV-Vis. A fuzzy comprehensive evaluation was carried out using membership function analysis. Results The optimal fertilizer treatments varied for different indicators and pharmacological components. Compared with the control group, the Fe1Mn2B2 treatment led to 96.82% and 162.67% increase in the diameter and length of C.dahurica(Turcz.) Maxim. rhizome respectively, the Fe2Mn0B2 treatment resulted in 73.72% and 79.01% increase in the accumulation of dry matter in the aboveground and underground parts respectively, the Fe2Mn2B3 treatment brought about 215.38%, 30.77%, and 224.74% increase in the contents of caffeic acid, ferulic acid, and total phenolic acid respectively, the Fe1Mn2B2 fertilization treatment led to 81.36% increase in the content of isoferulic acid. Based on the information of pharmacological component content, a fuzzy comprehensive evaluation was utilized to conduct a comprehensive assessment, and the optimal iron, manganese, and boron fertilizer ratio was determined to be Fe2Mn2B3, with fertilizer concentrations of FeSO4·7H2O 50 mg/L, MnSO4 30 mg/L, and Na2B4O7·10H2O 54 mg/L, and an application rate of 1 L. Conclusion The scientific fertilization scheme of iron, manganese, and boron can significantly increase the yield of C.dahurica(Turcz.) Maxim. and promote the synthesis and accumulation of active ingredients, which has certain guiding significance for the cultivation and production of C.dahurica(Turcz.) Maxim.. |
